Four in court over Sydney shootings

A Sydney man charged with shooting at a neighbour's residence and another man accused of shooting a teenager in the back will not be free on bail before their next court appearance.

The two men, along with two others charged with being accessories, are the first people arrested in connection with more than a dozen shootings across Sydney's west in January, nine of which occurred in eight days.

Ahmad Abdullah, 21, charged with shooting an 18-year-old man on Australia Day at Auburn, appeared in Burwood Local Court on Monday wearing a hooded jumper.

The victim, whose injuries were not life-threatening, refused to speak to police about the shooting.

Abdullah, a cabinet maker, was charged with shooting with intent to cause grievous bodily harm and three outstanding warrants.

He did not apply for bail, which magistrate Christopher Longley formally refused.

His co-accused, Ahmed Al-jubouri, 21, appeared in the same court charged with concealing a serious indictable offence and being an accessory after the fact.

He had appeared in the same court on Friday and was granted bail, which Mr Longley continued.

Ali Khaled, 25, and his girlfriend Shamiran Benjamin, 23, also appeared in Burwood Local Court on Monday over an unrelated shooting at Wiley Park.

Witnesses heard a man and a woman having an argument in Denman Ave, where Khaled lives, about 3.15am (AEDT) on Sunday, court documents allege.

The woman was seated in her Nissan Pulsar and the man was standing next to the vehicle.

Other witnesses told police that a shouting match erupted between a man fitting Khaled's description and a neighbour in a unit block.

The man retrieved a handgun, cocked the weapon, pointed it towards the unit block and fired once, the court documents state.

Detectives found a possible impact mark below a window.

Police say the woman then did a u-turn, the man got into the front passenger front seat and the pair drove away.

An unmarked Dog Squad vehicle stopped a Nissan Pulsar a short time later on the M5 motorway, and officers arrested Khaled and Benjamin and seized a loaded Glock 27 pistol from the vehicle.

The gun had a ten-round magazine containing seven 9mm rounds, with one round in the weapon's chamber.

Police retrieved a single bullet casing in Denman Ave that was identical in brand to the ammunition contained in the seized firearm.

Khaled and Benjamin had their clothes seized for forensic examination after they declined to talk to police.

Khaled appeared in court in prison greens charged with reckless discharge of a firearm in a public place and illegally possessing a firearm. He did not apply for bail, which was formally refused.

Police charged Benjamin with concealing a serious offence and being an accessory after the fact. She appeared in court wearing a blue, oversized police jumpsuit.

She was granted bail on the condition that she would not visit Denman Ave or approach any witnesses, report daily to police and keep a curfew between 9pm and 6am.

All four of the accused are scheduled to have their matters come before the same court on March 26.

Police launched Operation Spartan in mid-January, when nine shootings took place in eight days.

Before Sunday, the silence of witnesses and victims had prevented police from making any direct arrests over the shootings.

Operation Spartan has therefore targeted more than 150 people police believe may be linked to the shootings.

Search warrants and other police activity have led to 70 people being arrested, 200 charges being laid and more than 12 firearms being seized.
